Engineering (Apocalypse)

Engineering is the discipline of 'making stuff'.

Engineering Workshop Facility

The workshop is available as a Small facility in the beginning, and when the relevent research is completed, a Large facility will be an option. Placing small or large workshops would be ideally spread across all bases to limit the possibilty of losing all manufacturing capability if built only in one base.

Units

Technical personel may be hired with an education level of average to gifted. The better the skill of a engineer, the faster the construction project will be completed.

• minimum skill = 60
• maximum skill = 100
  

The total quantity of Engineers across all bases at any one time is fifty. If it is reduced for any reason, more Engineers will become available to be hired.

Manufacturing

A compact workshop base layout ...which will wipe out all manufacturing capability if it were to be lost.

These is nothing to built at the start!
X-Com will need to build more facilities in the future to enable the manufacture of advanced weapons, crafts and devices, armors, etc. Constructing an item will allow a profit to be made when sold on the market. Optimising production allows larger profits!

Completion And Timing

The timing to finish any project is always completed on the hour. Items with short build times should be optimised to best use the time by completing a manufacturing run just before the new hour, and is best when:

• Multiple small items built over a multiple day production run will more efficiently use workshop space and engineer skill instead of short stop-start projects.
• Massive projects, usually taking many days for just one item, should be planned as to not be forced to cancel the progress made since time spent and progress made on something that is canceled, is lost.
• Building something that can be recovered from a mission may not be the best use of the workshop. If nothing is needed to be built, build anything that gives the best profits.
• An idle workshop is wasting money! Get your money's worth!

Overheads

or, Costs Of Upkeep
Engineers receive a salary and maintenance of facilities (living and workshop) which will reduce your profits by a certain amount, each and every week. Once a project's profit is calculated without interuption (preferably over a whole week) it is then matched with the size of the facility being used, profit totals will become more accurate:

• Small Workshop costs = 250

Living quarters is half filled, so maintenance can be halved as well.

• Large Workshop costs = 500
  
• An idle workshop is inefficient! Make something even if it is barely profitable!

Flooding The Market

Every item is profitable to manufacture, but your sell price (and eventual profit) is determined by market forces. If you are selling so much (ie: flooding) that you drive the price down in the proceeding weeks, you will have to re-evaluate each manufacturing run using this new sell price of the new week, to find the best profits.

• Items recovered or built-in-bulk may be hoarded until the sell price rises if storage space is of no concern.
  

Items have differing amounts in the Market Capacity column which is a rough indicator of how many you can sell before you heavily influence the Sell Price towards its lowest value.
eg: selling x25 Dimension Missiles may slightly reduce the new-week sell price, but selling x25 Disruptor Guns will be classed as 'flooding' and will drive the sell price down, faster with a 'flood' every consecutive new week.

• An idle workshop is not making money! Swap manufacturing projects every week to avoid flooding the market with a single item.

Chart Definitions And Formulae

Note: Advanced Workshop = Large
Small Workshop = 500 total skill, maintenance 250 per week.
Large Workshop = 1000 total skill, maintenance 500 per week.

• Manufacture Item: no know = no no.
• Build Cost: Internal cost to build one item.
• Build Time: Internal time to build one item.

• Build Time H: Produce one unit in amount of hours (unrounded), based on Facility.

Build Time H = {Build Time ÷ Facility}

• Facility: Small (500) or Large (1000). Using Large to build Small items allows double production quantity and profit.
• Market Capacity: how much to sell before price starts to gets affected at the end of the week, every week.
• Sell Price: typical of the market.
• Raw Profit: sell one of something to get this amount of credit-dollars (disregarding maintenance costs or time taken to build).

• Profit Per Build Time: portion of a credit-dollar you get for each tick of the build clock (Facility irrelevant, not based on hours).

Profit Per Build Time = {Raw Profits ÷ Build Time}

• Profit Per Hour: money per hour dependant on Facility

Profit Per Hour = {Raw Profits ÷ Build Time H}

• Quantity Per Week: un-interrupted production in one week, 168hours (disregarding maintenance).

Quantity Per Week = {168 ÷ Build Time H}

• Profit Per Week: comparison of a total week production run which will depend of maintenance which is not included.

Profit Per Week = {Quantity Per Week × Raw Profit}
